What left side crank power meter for Sensah empire 2x11 with Zrace cranks?

Question for all,

my ltk-268 frame from longteng requires a bb86 bottom bracket.

I purchased a cheap bb86 from sigiyi/zrace with my crankset.

Is it worth paying 30-50$ to upgrade to a Shimano BB86 Bottom Bracket or something similar?

BB72-41 or RS500-PB

Just a head's up, I believe that Zrace spindle requires a DUB 29mm bearing set for the bottom bracket, so a straight swap with a Shimano bottom bracket with a 24mm bearing won't work. I'm not sure how many Chinese options there are for a DUB in the same spec, but other options are extremely limited and pretty pricey.

Is any BB upgrade worth it? Depends on what you are hoping to achieve. From what I understand, for press fit bottom brackets, creaking would bet he biggest issue.

Both ZTTO and ZRACE offer Dub BBs for PF86:

Update

I received the groupset.
My frame requires a bb86 bottom bracket.

The seller sent me a Zrace DUB bb92.

Will it fit?

The picture doesn't load on my mobile...
But if you zoom it should show 86.5-92mm would be fine.

Yeah, no worries, it'll fit.
